Biomarker assessment of organic matter sources and degradation in Canadian High Arctic littoral sediments

Carbon stocks in the High Arctic are particularly sensitive to global climate change and the investigation of the variation in organic matter (OM) composition is beneficial for improved understanding of OM vulnerability. OM biomarker characterization of solvent–extractable compounds and CuO oxidation products of littoral sedimentary OM in the Canadian Arctic was conducted to determine OM sources and decomposition patterns. The solvent–extracts …
